Description

The present invention relates to various knitted and knitted products such as gloves, socks and finger sacks used in sports, outdoor, light work, in shops / offices, homes, etc. Yarn and woven / knitted fabric itself, which have been given high anti-slip performance in particular, while imparting aesthetics to the product by utilizing the texture, appearance and functionality of the material and woven / knitted fabric structure The present invention relates to a technique for improving a feeling of wearing, detaching feeling and use feeling close to bare hands or bare feet.

As is well known, various types of textile products that have been considered to have anti-slip performance, in particular, glove products, finger sack products, and sock products, have been developed and provided as technical contents disclosed in each patent document to be described later. Has been. Hereinafter, the contents and problems of the prior art will be described in detail with reference to patent documents for each product.

(1) Glove products Patent Literature 1 and Patent Literature 2 disclose techniques for driving gloves. The glove for driving an automobile described in Patent Document 1 is provided with a plurality of protrusions made of rubber or synthetic resin on a non-slip part. This technology improves driving operability, but rubber or resin leaks inside the gloves during post-processing, so it feels soft and close to bare hands, and is lightweight and has a breathable, low-steaming mesh style. It is difficult to get a dough. On the other hand, the motorcycle riding glove described in Patent Document 2 sews a non-slip covering material, and can provide finger protection and heat-retaining properties. Discomfort due to stuffiness other than in winter is not improved.

Patent Documents 3 to 8 disclose techniques related to work gloves worn for various operations. First, according to the work glove described in Patent Document 3, the stretchable yarn is used to form a convex horizontal stripe pattern using a stretch difference with a fiber other than the stretchable yarn in the knitted structure. However, the concavo-convex portion is composed of fibers other than the elastic yarn, and the elastic yarn itself does not have an anti-slip effect. The glove having this configuration has a non-slip property by covering the palm portion with rubber or resin and has a strong feeling of coarseness. On the other hand, the glove described in Patent Document 4 maintains a grip force when wet by forming a film of rubber latex or resin emulsion in which spherical ceramic powder is blended on the surface of the glove. This has a strong feeling of coarseness and is suitable for heavy work but unsuitable for light work. Furthermore, the glove described in Patent Document 5 forms a non-slip film with a rubber latex or resin emulsion in which styrene-butadiene rubber powder is blended on the surface of the glove, and is not suitable for light work intended by the present invention. is there. Furthermore, the glove described in Patent Document 6 is a glove in which a number of minute recesses are formed on the surface of the anti-slip layer provided on the surface of the glove, and the glove described in Patent Document 7 vapor-deposits silicon resin on the surface of the glove. Furthermore, the glove described in Patent Document 8 has a glove surface coated with a foamed vinyl chloride resin film to obtain a non-slip effect. All of these are rough and have a problem that they are thin enough to cause material leakage and cannot be processed into gloves with rough eyes and cannot be expected to be freely stretchable. is there.

On the other hand, Patent Document 9 discloses a technique regarding sports gloves. The glove for sports described in Patent Document 9 is a highly adhesive glove using a natural rubber or synthetic rubber material rich in stretchability and waterproofness, and is effective in rainy weather. When used at other times, the feeling of stuffiness and lightness of the gloves does not improve the feeling of wearing or hindrance to movement.

Furthermore, Patent Document 10 discloses a technique related to cut-resistant gloves. The glove described in Patent Document 10 applies a non-slip material to a leather material, thermocompression-bonds, and imparts irregularities, and is suitable for handling glass or the like, but is coarse and inferior in wearing feeling. Therefore, it is not suitable for light work intended by the present invention. Patent Document 11 discloses a technique related to kitchen gloves. The glove described in Patent Document 11 is a non-support type glove and has an anti-slip effect, but has a stiff feeling and a feeling of wearing is not preferable. Moreover, since it adheres to a finger | toe and a hand, it has problems, such as being inferior to attachment / detachment.

(2) Regarding Finger Suck Products Patent Documents 12 to 15 disclose techniques related to finger sack. The finger sac described in Patent Document 12 is simply made of rubber, and the finger sac described in Patent Document 13 is a material in which a depression is provided on the surface of the finger sack made of a rubber material to improve the curling property of the paper surface. There is a finger sack provided with an air hole so as not to get steamed. All of these have a strong feeling of tightening, lack of softness, and a feeling of wearing is not good. On the other hand, the one described in Patent Document 15 is a free-size finger sack that can be attached with an optimum degree of tightening with respect to the finger size by an opening / closing tool, but lacks light weight and softness, and it cannot be denied that it is uncomfortable when worn.

As described above, most of these finger sacks have anti-slip performance, and rubber products are almost the only amber-colored appearance unique to rubber, the texture is rough and not breathable, and unsanitary Is something. In addition, due to the rough and hard texture, it is difficult to operate a calculator, a personal computer, and writing with a sack. There are a wide variety of product appearances, and there is no product that has a soft soft feel close to bare hands and a sufficient anti-slip effect.

(3) Regarding sock products Patent Documents 16 to 18 disclose technologies related to socks. According to the sock described in Patent Document 16, the method of changing the knitting structure of at least a part of the sole of the sock is intended to prevent slipping by the thickness or the knitting structure, and the effect is naturally weak. Because of the difference in thickness, you can't expect anything that is too comfortable to wear. On the other hand, the sock described in Patent Document 17 is a method in which inorganic particles are fixed to the sock by a dipping method to increase the coefficient of friction, and it is necessary to increase the amount of inorganic particles fixed in order to increase the anti-slip effect. As a result, the feeling of wear becomes poor and the feeling of wear is deteriorated. Furthermore, in the method of attaching a non-slip member made of rubber, soft plastic or the like to the grounding part of the sock in a dot-like manner as described in Patent Document 18, it is still rough and hard, and anti-slip effect is expected. Even if it is possible, a decrease in wearing feeling is inevitable. Furthermore, due to material leakage, it could not be used for thin and coarse fabrics and socks.

As described above, conventional gloves, finger sack, and socks are rubberized processed products made of inexpensive cotton fibers, synthetic resin impregnated processed products, or rubber products (natural, synthetic), which have sufficient functionality. The appearance of the product does not leave the area for rugged work. No product has been developed that is fashionable or hygienic to stimulate new demand.

Therefore, the present invention has been made to solve many of the problems found in the prior art described above, and is not a rough product form such as a rubber product or an anti-slip material film product, but comprises them. The yarn itself is provided with anti-slip properties, and a knitted or knitted fabric made of such yarn is provided, and the anti-slip effect is maintained in the product itself by using this yarn, and a feeling of wearing and a feeling of desorption are provided. Furthermore, the present invention provides a novel glove, finger sack, and socks that have a good feeling of use and express a touch as close to bare hands as possible and a stylish appearance.

In order to achieve the above-described object, the present invention, specifically, the traveling tension ratio T2 / T1 (the traveling tension ratio is obtained by dividing the outlet tension T2 when the yarn is traveling at 10 m / min by the inlet tension T1. Value) is a composite twisted yarn of a high friction fiber having a running tension ratio equal to or less than that of a high friction fiber having a running tension ratio of 2.00 or more, and the high friction fiber is characterized by sticking to the outside of the low friction fiber. It constitutes a composite twisted yarn having anti-slip properties.

Furthermore, according to the present invention, a composite twisted yarn having anti-slip properties in the form of a covering yarn in which at least the sheath yarn is composed of high friction fibers is formed.

Furthermore, in this invention, it is a twisted yarn of high friction fibers and low friction fibers, and constitutes a composite twisted yarn having anti-slip properties in which the low friction fibers are entangled yarns or twisted yarns.

Furthermore, in the present invention, a slip yarn which is a twisted yarn of a high friction fiber and a low friction fiber, wherein the low friction fiber is a spun yarn and is twisted in the same direction as the original twist of the spun yarn. It also constitutes a composite twisted yarn having preventive properties.

Furthermore, the present invention also constitutes a composite twisted yarn having anti-slip properties, characterized in that the high friction fiber is a polyurethane yarn or a rubber yarn.

Furthermore, the present invention is characterized by a knitted or knitted fabric having anti-slip properties organized by the above-described composite twisted yarn.

Furthermore, in the present invention, the above-described composite twisted yarn constitutes an anti-slip glove, finger sack, and socks.

According to this invention, first of all, it is possible to provide a composite twisted yarn having anti-slip performance that has a novel structure as defined in claims 1 to 5, and to make a structure using this composite twisted yarn. Thus, it can be said that the knitted and knitted fabric having the anti-slip performance is used, and it is extremely effective in providing the glove, finger sack, and socks having the anti-slip performance. According to this invention, in addition to providing an effective product having anti-slip performance, gloves, socks, and finger sacks having the following effects as compared with conventional products can be obtained.
(1) By using a composite yarn with improved anti-slip performance while reducing the amount of polyurethane and rubber yarns used, it is possible to minimize tension fluctuations during adult knitting, high-quality woven and knitted fabrics, and various products. Is easily obtained.
(2) The amount of polyurethane yarn and rubber yarn used can be greatly reduced, and a low-cost product is possible.
(3) Since the yarn / woven / knitted fabric structure suppresses the stretchability and tightening force of the product, the gap between the organized yarns can be increased, and the product can be easily obtained in a large size, thin, lightweight and air-permeable. .
(4) In addition, a product that has a natural fit and a gripping feeling close to bare hands, and extremely good work efficiency can be obtained.
(5) A washable product is obtained, which is comfortable and hygienic.
(6) It is possible to use an original or formed polyurethane yarn as a fiber having anti-slip property, and a yarn formed or dyed as another fiber, and in addition to the above characteristics (1) to (5), a conventional product Composite yarns, knitted fabrics, and products with unprecedented color and high fastness are possible.
(7) Applicable to the following applications having the above characteristics.
Gloves and finger sacks for use in home delivery / moving work, offices, stores, and homes where you can write letters, turn paper, and operate PCs and calculators easily.
Light sports gloves such as golf and baseball, outdoor gloves such as hiking, camping and fishing, gardening gloves and finger sack.
Driving gloves for cars, motorcycles, bicycles, etc.
Finger sack, gloves and cut resistant gloves for assembly work of parts and machines.
Gloves for handling glassware, ceramics, antiques, arts and crafts, vases and books, and dishwashing.
Socks that are worn effectively for sports, outdoor, business, casual, pregnant women, elderly people, infants and children.

In order to obtain a target product, the present inventors have devised that anti-slip performance is obtained by increasing the proportion of high friction fibers in the composite yarn of high friction fibers and low friction fibers. For example, a thicker rubber thread or polyurethane thread is used as the core thread, and the sheath thread is finer than the core thread, and the rubber thread or polyurethane thread is exposed on the surface of the composite thread to prevent slipping. It is intended to obtain composite yarns and knitted fabrics with stopping performance, and gloves and socks composed of them.

Conventionally, high-friction fibers represented by polyurethane yarns and rubber yarns are generally excellent in stretchability, so they have been arranged in the core yarn and generally used as a stretchable yarn structure covered with other fibers that are sheath yarns. Is. In the technology of Japanese Patent Application No. 2003-271830 applied by the same applicant, high friction characteristics such as polyurethane yarn or rubber yarn are actively used for the purpose of obtaining a non-slip effect. Since it is thicker than the yarn, it has high stretchability and easily causes tension spots due to contact with the guide and yarn path during knitting, and there are some problems with the knitting property, product quality, and excessive tightening of the product. Further, in these composite yarns, since the low friction fibers inhibit the anti-slip effect, it is necessary to increase the proportion of polyurethane yarns or rubber yarns that are high friction fibers, resulting in high cost.

In order to overcome these problems, in the present invention, the fineness configuration of the core yarn and the sheath yarn is mainly reversed, that is, the low-friction fiber 1 having a large fineness is disposed on the core yarn, and the high-friction fiber 2 having a thin fineness is disposed on the sheath yarn. Is used as a composite yarn. This method can suppress the stretchability of the composite yarn, improving the knitted fabric, the quality of the knitted fabric and the product and the tightening property of the product, and further reducing the cost by reducing the mixing ratio of the high friction fiber, and the composite The anti-slip effect can be increased by increasing the surface area of the high friction fiber with a low mixing ratio in the yarn.

In this invention, after dyeing the low-friction fiber, it is possible to avoid contamination of the rubber yarn and the polyurethane yarn by using a high-friction fiber and a composite yarn having color by means such as covering and twisting, and robust color properties A composite yarn is obtained. Further, by using a rubber yarn or polyurethane yarn containing carbon or pigment, a robust color composite yarn having the same color or different color effect can be obtained.

The high friction fiber in the present invention is a fiber having a running tension ratio T2 / T1 of 2.00 or more, and the running tension ratio means that the yarn Y from the sample source 5 is run at 10 m / min in FIG. The outlet tension T2 is divided by the inlet tension T1. The knitting needles 6 and 6 may be commercially available products, and are arranged so that the yarn Y runs through the two needles 6 and 6 at a right angle. The value of the product is generally higher than the value of the raw yarn because weaving is performed after weaving or after the product, and the softening agent and the smoothing agent of the raw yarn oil agent and composite yarn are removed. High-friction fibers include rubber yarns and polyurethane yarns, but of course they are not limited to these fibers. When the running tension ratio is less than 2.00, it is difficult to obtain an anti-slip effect. Preferably it is 2.2 or more.

Low friction fiber refers to a fiber having a running tension ratio T2 / T of less than 0.200. Natural fibers such as silk, wool, cotton or hemp, and regenerated cellulosic fibers such as rayon, as well as esters, nylon, acrylic and polyethylene. , Synthetic fibers such as polypropylene and polyvinyl chloride, super strong fibers (aramid fibers, ultra high molecular weight polyethylene fibers, fully aromatic polyester fibers, etc.) and the like. Regardless of long fiber or short fiber type, fiber form such as cross-section / additive, yarn form such as spinning or spinning and production method, the fiber is an ultraviolet light inhibitor, heat storage material, deodorant, antibacterial / antibacterial agent, chitosan, It may contain collagen, protein, etc., and may be a hygroscopic exothermic type or ultrafine fiber. The anti-slip effect of the composite yarn may be enhanced by mixing Y-shaped or cross-shaped cross-section fibers.

Examples of the form of the composite twisted yarn in the present invention include a form having a twisted structure such as covering CY and twisted yarn TY. The proportion of high friction fibers in the composite yarn in the present invention is preferably 65% or less, and more preferably 55% or less. In the covering yarn form in which the surface of the composite yarn is actively covered with the sheath yarn, in the present invention in which the high friction fiber is used as the sheath yarn, the surface area of the high friction fiber can be dramatically increased. Furthermore, it is possible to make it 40% or less. As in the examples, it becomes possible to reduce the fineness and the mixing ratio, and it can be adopted as a manufacturing method having a large economic effect. The core yarn may be a long fiber untwisted / unentangled yarn, a twisted yarn, an entangled yarn, or a short fiber. These mixed yarns may also be used. The short fiber may be an air entangled spun yarn such as an open end method or a bundle spun in addition to the ring spun yarn. The covering method may be single covering, but may be double covering.

Long fibers and short fibers can be used as the low-friction fiber in the twisting method. They may be untwisted / unentangled yarns, but twisted / entangled yarns are more preferable because the high-friction fibers are more likely to stick to the low-friction fibers and the proportion of the high-friction fibers can be reduced. In the case of twisting using low-friction fibers as twisted yarn, twisting in the same twist direction is more preferable than twisting in the opposite direction to the twisted yarn for the same reason.

The role of the high-friction fiber in this invention is to prevent slipping and not to stretch. The composite yarn having high stretchability makes it difficult to manage the tension during adult knitting, deteriorates the quality of the woven or knitted fabric and the product, and finishes the product with a strong feeling of tightening. For this reason, it is preferable that the draft of the high-friction fiber at the time of producing the composite yarn is 2.0 times or less, more preferably 1.5 times or less. Thus, by reducing the draft of the high-friction fiber and at the same time reducing the mixing ratio, it is possible to suppress the stretchability and the tightening property of the product at the time of product manufacture. Therefore, a large inter-yarn gap can be secured, and a lightweight and woven or knitted structure having a large gap such as a mesh can be easily expressed. This makes it easy to design products that take advantage of these characteristics and are rich in design.

The number of twists in the covering yarn or the twisted yarn is 200 times / m or more and 1,500 times / m or less, more preferably 1,000 times / m or less, and is arbitrarily set. If it is less than 200 times / m, the proportion of the high-friction fiber exposed to the surface of the composite yarn or the woven / knitted fabric decreases, and it is difficult to obtain the anti-slip performance, and the stretchability is exhibited, which is not preferable. Further, at 1,500 times / m or more, excessively high-friction fibers become too tight, or in order to obtain a uniform appearance, it is necessary to use a fine yarn, which is cost and strength (product durability). It is disadvantageous because it is disadvantageous. When a twist set is necessary, it is preferable to perform a low temperature set of 70 ° C. or less to prevent a decrease in strength of the high friction fiber. In any composite yarn, the use of a composite yarn having a high number of twists and a high degree of entanglement as a low-friction fiber can give a sense of sharpness, and it is possible to obtain a cool product having a large gap between yarns.

For the purpose of improving the synthetic knitting property of the above composite yarn, a smoothing agent or the like may be added to the composite twisted yarn product. By removing these together with the raw yarn oil agent in the washing process of the product, the anti-slip performance of the composite yarn can be restored, and the anti-slip performance inherent to the original yarn without oil agent adhesion can be improved.

The composite yarn may be knitted or knitted alone or with other fibers during synthetic knitting. The composite yarn may be knitted by knitting other fibers so that many other fibers are in contact with the side in contact with the skin, or a woven structure with back and front such as satin or twill may be used. The determination may be made in consideration of the anti-slip performance of the composite yarn and the product, the functionality of other fibers (heat retention, quick drying, breathability, etc.), texture, appearance, and the like.

The product may be a dedicated sock knitting machine, glove knitting machine or finger sack knitting machine. For example, as shown in FIG. 2, the glove 21 has its finger part 22 and palm part 23 knitted with the composite yarn, and the sock 11 has its toe as shown in FIG. The part 12, the arch part 13, and the heel part 14 may be knitted all or part thereof with the composite yarn, and in the finger sack 31, the whole may be knitted with the composite yarn. In addition, a knitted fabric having anti-slip performance may be cut, and woven fabrics having anti-slip performance and different designs may be sewn together. Other woven or knitted fabrics may be used for the parts. Hereinafter, the present invention will be described in detail based on preferred embodiments.

Silk spun 60 Ne twin yarn (177d, 197 dtex, twin twist direction is S) scoured and softened to the core yarn, and polyurethane yarn 78 dtex (running tension ratio T2 / T1 = 2.75) is used as the sheath yarn, The polyurethane yarn wound on the bobbin was covered at 500 times / m in the Z direction with natural unraveling tension applied during covering. The appearance of the finished composite yarn was moderately tightened by the resilience of the polyurethane and was uniform. The blend ratio was 50.7% for silk spun yarn and 49.3% for polyurethane yarn. The elongation percentage was 14.8% (JISL1090A method compliant, initial load 0.001 g / d, measurement load 0.20 g / d), and the elongation of the yarn was less than that of Comparative Example 1. After applying a smoothing agent to the composite yarn, it was knitted with a 15 gauge glove knitting machine. The knitting property was not particularly problematic. Although the obtained glove had a slight slime feeling, the slime disappeared from the dried glove after washing with a washing machine using a detergent and dehydrating. The gloves are thin, lightweight, soft and have a good fit, and have an anti-slip effect. You can easily turn over the pages of commercially available notebooks and books, and easily write letters with a pen while wearing them. I was able to. Gloves suitable for handling tableware, glassware, antiques, vases, arts and crafts, books, newspapers / flyers, stationery, etc. that are slippery with sweat and oil in the hands in offices, stores and homes were obtained.

In Comparative Example 1 related to Example 1 above, the same polyurethane yarn 77dtexT as in Example 1 is used as the core yarn, silk spun 60Ne twin yarn (S twist) is used as the sheath yarn, and the core yarn has normal stretchability. The draft was obtained at a draft of 3.5 times, and a covering yarn was obtained while twisting 500 times / m in the S twist direction. The blend ratio of the composite yarn 244dtex (220d) was 80.5% for silk spun yarn, 19.5% for polyurethane yarn, 38% stretch rate, and was highly stretchable. The knitted fabric produced in the same manner as in Example 1 has a large knitted fabric shrinkage after washing, and is reduced to a size of about 75% as compared with Example 1. For this reason, the feeling of tightening after wearing was tight, and uncomfortable feeling was superior to feeling the silk feeling for wearing for a long time. Naturally, the product did not have anti-slip performance, and it was difficult to flip the pages of commercially available notebooks. In order to obtain a glove having the same size as that of Example 1, it is necessary to knitting about 25% larger, which increases the product weight, loses the light weight, and further increases the cost.

In Example 1 above, the fineness of the sheath yarn was replaced with 156T (running tension ratio T2 / T1 = 2.90), and the core yarn was replaced with ultrahigh molecular weight polyethylene fiber (Toyobo Co., Ltd., Dyneema (registered trademark)) 440T. A covering yarn was obtained under the same conditions. The appearance of the composite yarn was uniform with the sheath yarn in close contact with the core yarn. The mixing ratio was 27.0% for polyurethane and 73.0% for Dyneema (registered trademark). The yarn elongation was almost 13.0%. After applying the smoothing agent, gloves were knitted with a 7 gauge glove knitting machine. The gloves obtained through the same process as in Example 1 were soft and had anti-slip performance. Compared to a rubberized product on the palm of a glove knitted with Dyneema (registered trademark) alone, there is no feeling of coarseness, so there is a sense of grasping an object with bare hands, and there are several in terms of accuracy of wearing feeling and workability It was a step win. Since it is easy to write a letter with a glove attached, it can be suitably used for moving work, courier loading and delivery work, machine / part assembly work, and the like.

Nylon 6 false twisted yarn 56T48f is used as the core yarn, and the sheath yarn is polyurethane 33T [melt-spun low temperature setting polyurethane fiber ESPA M (registered trademark) manufactured by Toyobo Co., Ltd., running tension ratio T2 / T1 = 2.84 ] Was used in the same manner as in Example 1 except that the twist number was changed to 700 times / m. The blend ratio of the obtained composite yarn was 61.2% for nylon and 38.8% for polyurethane. A circular knitted fabric was produced with a tengu structure (28 gauge) using the composite yarn and one nylon 6 false twisted yarn 78dtex68f alternately. Subsequently, the dough was scoured and washed, dehydrated, and subsequently expanded into a cloth and subjected to a dry heat set at 140 ° C. for 40 seconds. The fabric was set at the same time as the skewing property was eliminated, and the fabric became a fabric with reduced elasticity. The proportion of the polyurethane fabric was 20.5%. After that, it was cut and stitched into a glove. The product was thin, had no tightness, had a soft touch and good fit, and had sufficient anti-slip properties. Further, since the product is composed of hydrophobic fibers, it has washer-and-wear properties and excellent cleanliness. Suitable for the same application as described in Example 1, and a cheaper product is possible.

The finger sack was knitted with a flat knitting machine for finger sack so that the composite twisted yarn product of Example 3 and refined silk spun 60Ne (98.4 dtex) were drawn together and the silk spun was in contact with the skin side. The sac was washed and dehydrated, fitted into a finger mold, and subjected to a dry heat set at 130 ° C. for 30 seconds to obtain a product. The finger sack is thin, lightweight, soft to the touch, has a natural fit without tightening, and has sufficient air permeability and anti-slip properties. Raw silk is a material that has antibacterial properties and is familiar to the skin, and is a product that can handle a personal computer, a calculator, a pen, and office supplies with the same feeling as a bare hand while wearing the finger sack. It can be easily washed at home or office, dehydrated, or squeezed between handkerchiefs and towels to squeeze out moisture and re-install / reuse without taking time, thus maintaining the cleanliness. there were.

Twisting number in the same manner as in Example 1 except that the polyester false twisted yarn 500dtex 144f dyed with black cheese is used as the core yarn and the black original polyurethane yarn 156dtex (running tension ratio T2 / T1 = 2.35) is used as the sheath yarn. Covering was performed 500 times / m to obtain a composite yarn (540 dtex) of 24.2% polyurethane and 75.8% polyester. Gloves were knitted with a 10 gauge knitting machine using only the composite yarn. The composite yarn had an elongation of 7% and good knitting, and there was no problem in product quality. The glove after washing and drying is soft, lightweight, breathable and cool, has a strong anti-slip performance for a low polyurethane blend ratio, and is suitable for golf and baseball gloves that require a strong grip. Finished on gloves. In these sports applications, gloves are heavily soiled by hand sweat, oil, dirt, golf shafts, gloves, bats, etc., and conventional natural leather and artificial / synthetic leather cannot be easily washed and are unsanitary. In the present invention, repeated cleaning can be easily performed, and after dehydration or by inserting gloves with a handkerchief or towel and squeezing out moisture, it can be reattached without taking time, so it is comfortable and hygienic. The present invention can also be used for the applications described in the first embodiment.

After blending cotton 60Ne (original twisted Z direction) and the same polyurethane 78dtex as drafted 1.2 times, twisting 500 times / m in the Z direction with a ring twister, 60 ° C for 30 minutes Wet and heat set. The composite yarn had a blend ratio of 45.2% polyurethane and 54.8% cotton, and was in the form of a yarn in which the polyurethane yarn stuck to the surface of the composite yarn. Cotton yarn 60Ne (S twist 1600 times / m, 85 ° C., 40 minutes wet heat set) was plated on the composite yarn, and socks were knitted. The obtained socks had anti-slip properties, had a refreshing feeling peculiar to strong twisted yarns, had little stuffiness, and were comfortable to walk on the floor, tatami mats, stairs, etc. A sock made of a strong twisted yarn is comfortable to wear, but it is disadvantageous in that it is slippery and dangerous. Suitable for business and casual use.
